Endoscope fixing structure

Abstract

An endoscope fixing structure mainly includes an endoscope, an image pickup assembly, and a fixing member. The endoscope is extendable into a nasogastric tube. The image pickup assembly is arranged at an end of the endoscope. The fixing member is arranged at one side of the endoscope that is opposite to the image pickup assembly. The fixing member includes a front end portion and a rear end portion having a cross-sectional area greater than the front end portion and is thus fixable to an opening of the nasogastric tube by means of the rear end portion to constrain movement of the endoscope. To combine the endoscope with the nasogastric tube, the image pickup assembly is first inserted into the nasogastric tube, until retaining engagement is induced between the fixing member and the opening of the nasogastric tube. This achieves fast fixing of the endoscope to the nasogastric tube.

I claim: 
     
         1 . An endoscope fixing structure, mainly comprising:
 an endoscope, which is extendable into a nasogastric tube;   an image pickup assembly, which is arranged at an end of the endoscope; and   a fixing member, which is arranged at one side of the endoscope that is opposite to the image pickup assembly, wherein the fixing member comprises a front end portion and a rear end portion having a cross-sectional area greater than the front end portion, so that the fixing member is fixable, by means of the rear end portion, to an opening of the nasogastric tube to constrain movement of the endoscope.   
     
     
         2 . The endoscope fixing structure according to  claim 1 , wherein an inclined portion is arranged between the front end portion and the rear end portion. 
     
     
         3 . The endoscope fixing structure according to  claim 2 , wherein a cross-sectional area of the front end portion is smaller than a cross-sectional area of the opening of the nasogastric tube. 
     
     
         4 . The endoscope fixing structure according to  claim 3 , wherein the cross-sectional area of the rear end portion is greater than the cross-sectional area of the opening. 
     
     
         5 . The endoscope fixing structure according to  claim 2 , wherein at least one rib is formed on the inclined portion. 
     
     
         6 . The endoscope fixing structure according to  claim 1 , wherein the image pickup assembly comprises an image pickup lens, at least one light-emitting element arranged at one side of the image pickup lens, and a signal transmission element arranged at one side of the image pickup lens. 
     
     
         7 . The endoscope fixing structure according to  claim 6 , wherein the signal transmission element comprises one of wired transmission and wireless transmission. 
     
     
         8 . The endoscope fixing structure according to  claim 6 , wherein the signal transmission element is in information connection with a display device. 
     
     
         9 . The endoscope fixing structure according to  claim 1 , wherein the nasogastric tube is formed, in an end, with an end opening to allow the image pickup assembly to pick up an image outside of the nasogastric tube. 
     
     
         10 . An endoscope fixing structure, mainly comprising:
 a fixing member, which is arranged on an endoscope that is extendable into a nasogastric tub, wherein the fixing member comprises a front end portion and a rear end portion having a cross-sectional area greater than the front end portion, so as to be fixable to an opening of the nasogastric tube to constrain movement of the endoscope; and   a combining portion, which is arranged on the fixing member to receive the endoscope to attach thereto or detach therefrom.   
     
     
         11 . The endoscope fixing structure according to  claim 10 , wherein an inclined portion is arranged between the front end portion and the rear end portion. 
     
     
         12 . The endoscope fixing structure according to  claim 11 , wherein a cross-sectional area of the front end portion is smaller than a cross-sectional area of the opening of the nasogastric tube. 
     
     
         13 . The endoscope fixing structure according to  claim 12 , wherein the cross-sectional area of the rear end portion is greater than the cross-sectional area of the opening. 
     
     
         14 . The endoscope fixing structure according to  claim 11 , wherein at least one rib is formed on the inclined portion.
